Application filed April 5, 1905'. "Serial No. 254,237.

of New York, have invented a new and Im-; proved Pneumatic Brush-Filling Machine, of which the following is a full, clear, and exact description.

My invention relates to brush-filling machines, and more particularly to mechanism for manipulating the bristles by means of a rcurrents.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters ofreference. indicate corresponding parts in all the ures.

Figure 1 is a perspective view of a machine embodying my invention and ready for use. Fig. 2 is an enlarged side elevation, partly broken away, of one of the brush-filling dies and its accompanying parts removed from the table. Fig. 3 is an end elevation, also enlarged, showing the die and its accompanying parts removed from the table. .Fig. 4 is a front elevation, artly in section, showing the dies as space apart andindicating by arrows the course of the air-currents; and Fig. 5 is a fragmentary plan view of the table with the dies mounted thereupon and spaced apart.

The table is shown at 4 and is provided with supporting-legs 5. A receptacle 6 depends from the table 4 and is connected by an air-conduit 7 with a blower 8,whichis propelled by means of a power-belt 9., From the blower 8 another air-conduit 10 leads upward through the table 4, and revolubly mounted upon its upper end is an elbow 12, connected thereto by means of a swivel-joint 11. The elbow terminates in a pyramidal nozzle 13. Immediately back of the table 4 is a box 14, used for purposes hereinafter" mentioned. Mounted upon the table are supporting-rails 1 5, intermediate of which is a comparatively wide slot 4 A die 1s shown at 16 and is provided with a concavity 17 and with a number of bristle-holes 18, extending through the die and merging into the concavity. Each bristle-hole 18 terminates in an aperture 19 of frusto-conical shape. The die 16 is provided with dowel-holes 20 and with depending lugs 21 22 of the shape indicated. A coffin 23 is.closed at its top by means of a wire sieve 24 and is provided with dowel-pins 25, which pass into the dowelis provided with a s10 ing edge 27 and with aclamp 28,'the clamp fi body, of the shield. The upper portion of theclamp28 is provided with folds 29, diseing integral with the posedu on opposite sides of the die 16 and adapte to engage the same so as to secure the bristle-shield 27 directly in position, as indicated in Fig. 3. The lugs 21 serve to prevent the shields from being moved laterally by means of the air-currents or otherwise displaced from any cause.

The operation of'my device is as follows: The operator stands in front of the table 4, while the machine is in action. He scatters bristles loosely over the several dies, and the blower 8 being in motion the bristles are drawn downwardly by air-currents and pass through the air-conduit 7 to the blower 8,

thence through the air-conduit 10 to the noz- =zle 18, whence they are forcibly driven downward uponthe several screens 24 and also intermediate of the several dies.' A great many of the bristles by falling through the screens 24 land upon the die in such position as to stand vertically within the bristle-holes 18, and the dies are thus filled. The operator constantly Whisks from the tops of the screens 24 any bristles which may happen to lodge in horizontal position, and such of these bristles as drop endwise through these screens are apt to lodge vertically within the bristle-holes 18. The excess of bristles is constantly whisked 03 intermediate of the dies into the air-spaces and is again carried through the pneumatic conduits 7 10 and then showered upon the screens 24. The several dies having been filled the operator removes them. He next takes off the coflin 23, carrying the screen 24, and then rests a board'orplate upon the up er surface of the die 16 and quickly inverts both the board or the plate and the die. This leaves numerous bunches of bristles protruding through the holes 18 into the concavity 17 of the die. The

operator then fills the concavity 17 with plastic material so as to embed the ends ofthe bristles, removes the member thus formed,

and otherwise proceeds with the manufacture of the brush, the several subsequent steps being old and well known. The die forms no part of the brush.

If desired, the several dies can be placed close together, so as to prevent the bristles from entering the hopper 6 to any great exholes 20, thereby holding the cofiin 23 securely n positionupon the die. A bristle-shield 26 sirable to distribute the bristles by hand.

upon the screens 24:. and-to have the machine remove the superfluous bristles to'someother; point. In orderto accomplish-this-result, the

elbow.12 and the hopper Glare swung around to the'position indicatedfby dotted'lines'im Fig. 1.,the bristles falling into the box 14;, whence they may be removedat willfby theoperator.

It should be understood; of: course, that-1 loose bristles may be'filled into the brushes.

byhand, or partially by the aid'of mechanism.

Iconsider it. desirable, therefore, tohave the machine so constructed that itmay blow the bristles downward upon. the screens 24', wherefthe bristles are fed? into the machine by. hand, or to draw the bristles downward: into the ho per 6'by suction whenfedf by hand upont I e screens 24, or to both blow thev bristles downward upon the-screen24 andremove the superfluity by means of suction. through the hopper: 6, as desiredby the op,- erator.- I recommend that in all instances the operators stand by. the machine with awhisk-broom or analogous member inhandl and that he occasionally assist; the machine in. case-anything should go wrongwith thefalling bristles.

Having thus described my invention, I claim. as new and desire to secure by Letters Patent 1. In a brush-filling machine, thecombination of adie provided Withapertures iorhold; ing-tuits ofjbristles, a bristle-shield provided with clamps engaging said die, said' bristleshieldbeing supported by. said clamps so as to dependlfrom saiddi'e, and meansfor show.- ering bristles upon said die;
